摘要
常规风机节能理论算法在计算火电机组一次风机的变频改造效果时,存在因忽略设备实际运行特性而导致计算偏差较大。为此,提出一种基于风机实际运行出力反推节电率的算法模型,对常规风机节能理论算法进行了修正,并结合设备具体情况及实际运行数据进行分析。结果表明:该算法能够准确反映风机变频改造后的节能效果。
When assessing the energy-saving effect of variable frequency drive retrofit for primary fans in thermal power units using conventional theoretical energy-saving algorithms for fans,significant calculation deviations often occur due to overlooking the actual operating characteristics of the equipment.To address this issue,an algorithm model based on the actual operating output of fans to deduce the electricity-saving rate is proposed,providing substantial supplementation and correction to the conventional theoretical fan energysaving algorithm.Simultaneously,analysis was conducted considering specific equipment conditions and actual operational data.The results indicate that this algorithm can accurately reflect the energy-saving effect after the variable frequency drive retrofit of fans.
